So where's the picture?

he says: "manufactured on tungsram equipment by JJ"

so the only thing RCA about them is the box, most likely.

Oh dear. Seems that JJ/Tesla has acquired the right to use the RCA name.

Brace yourselves, here comes the confusion, lads!

Cheers,

Hi RATs!

Never mind the confusion, the tube bidness has always been a bit heavy on the
bidness end and light on the product purity end

Anything which sells more tubes is wonderful.

In one of his other auctions for the JJ EL34's, he states they were
made on Mullard and Siemens equipment...

he says: "manufactured on tungsram equipment by JJ"

so the only thing RCA about them is the box, most likely.

thats so ****in' goofy..

some greedbags aquire the name svetlana in the US (& britain?), so the
company that has been named this for ~ 100 years doesnt have rights to it in
the US.. so they call 'em "winged C" haha

should just call em ó×ÅÔÌÁÎÁ, their real name..

(/me doubts the cyrillica will show up..)

yes, I completely agree, it is an outrage!

we can vote with out wallets though, don't buy anything from the greedbag
company (New Sensor), make sure you ask you tube supplier not to either,
also don't buy anything marked "Sovtek" or Electro-Harmonix" (both names
owned by the greedbag New Sensor firm) and of course, don't but the
Svetlana labeled tubes (really just crummy Sovteks)

insist on real St. Petersburg built S.E.D. "Winged C" tubes from a dealer
that no longer deals with the New Sensor firm

if this last part is impossible, I may have to start selling new production
tubes to give people an ethical source (I won't be selling anything Sovtek
or Electro-Harmonix)

A. The company known as "RCA" actually no longer exists in the form
that was a rival/partner to GE in the USA. Afaik.

B. The brand name afaik is controlled by GE or some other corporate
entity and has licensed it to various companies to make various products
that bear the RCA name. Like TVs...

C. Actual RCA tubes were made in New Jersey.

D. Most of this equipment went to Richardson.

E. Some of it went to other domestic locations and individuals, but not much.

F. What did not go to Richardson went to the junk yard for scrap (most actually),
while some went to Europe - mostly Eastern Bloc countries. And apparently a fair
amount went over to China.

Now, even if you actually had the original specs and the original blueprints, and
the original formulas AND the original line for a given tube, you still CAN'T
actually make the identical tube that RCA did (or anyone else did). Because
you can't get the same parts from the same vendors. Most of the original
vendors for specialty parts don't exist, and were domestic US companies.

The main issue is the chemistry. The chemistry is an art, not an exact receipe
either. Talking coatings and their mixing, as well as the application and "curing."
Hard to do an RCA tube without RCA people who did this task.

The best you could do, sitting in Eastern Europe or China - even if you have
a fair amount of a given line - is to make a good copy that is reasonably faithful
to the original design. Probably you have to reverse engineer an RCA tube and
try to duplicate it.

Merely sucking the air out of a tube on what was FORMERLY an RCA sealex
machine doesn't make it an RCA by any stretch of the imagination. (etc.)

In the first place, many of these machines were actually converted from EDISON
plants that made lightbulbs!! Heh heh.

Also, the jigs that sit on the Sealex machines are unique to each tube and each
manufacturer, and maybe to each machine's set up (assuming more than one
machine running the same tube). So, chances that they had the original jigs
are slim and none.

But, that doesn't mean that it isn't a kick ass good tube... or that it is.

(these days the process in theory should be *better* in some ways - like vacuum
and computer controls)

No, it's Thomson. You can look it up, like I did, at www.rca.com
Thomson owns the rights to the RCA name in the Western Hemisphere
(except possibly Canada?)
Thomson-RCA did sell a lot of tubes never made by RCA in genuine RCA
boxes, as they're legally entitled to do.

Outside the Americas, IIRC, STC had the rights to the RCA name
in the UK and Amalgamated Wireless had it in Australia.
Elsewhere, I don't know.


C. Actual RCA tubes were made in New Jersey.

RCA also made tubes in Mexico and Chile. The Chilean ones
I've seen were almost dead ringers for the US made ones.
Mexican ones look like Japanese tubes.

Merely sucking the air out of a tube on what was FORMERLY an RCA sealex
machine doesn't make it an RCA by any stretch of the imagination. (etc.)

That I agree with. They're not car fenders, just having stampings
from the original dies doesn't in itself mean anything.

Probably not in RCA's case, since RCA didn't make light bulbs that
I know of.

And here in Australia sells a range of A/V products (discmans, boom boxes,
DVD players, TVs, digital set-top boxes etc) variously branded RCA (usually
cheapest), Telefunken (which they also own) and Thomson.

Outside the Americas, IIRC, ..... Amalgamated Wireless had it in

Correct. The valves/tubes were often branded "AWA Radiotron".

And bloody ripper toobs they were too!

Hi Ned,

C. Actual RCA tubes were made in New Jersey.

RCA also made tubes in Mexico and Chile.

Maybe Brazil, too? Just in front of me I have
2 NOS/NIB 6FQ7/6CG7 (both type names present
on the box and the glas envelope)

Red boxes "RCA Valvula Eletronica", printed on them:

Fabrica Av. Gal. DAvid Sarnoff No. 3113
Contagem - M.G.
(long C.G.C number)
Industria Brasileira

On one flap:

RCA
Componentes
Electronicos

Marca Registrada
Made in Brazil

Red ink on the glas envelope, saying:

RCA
Industria
Brasileira

and 2 octogons (one red, one gray) with

6FQ7
6CG7

in them, and

BRAZIL

under them.

Production time code says:

676

The tube have side getters and dark grey to black
plates.

I can put photos of them & their boxes on my
homepage, if you want to have a close look.

Besides this, they measure like new and will
probably go into my over-next tube project :-)

Sure sounds like RCA had a Brazilian tube operation..
after all, I doubt the city of Contagem would name a
street after RCA's president (David Sarnoff)
if the place was just a warehouse! Also, "Fabrica"
is Portuguese for "factory".

I have some Brazilian *boxed* RCA 12BH7 that have
boxes identical to what you describe, but they're
overstamped "Procedencia Estrangeira" (foriegn origin)
and the tubes inside were made in Mexico.

And here we have a 5R4GY "RCA Electron Tube, Made in Italy"...

OK, OK, the boxes reveal that it was made by ATES (Aziende tecniche
elettroniche del sud SpA) under RCA license.
